It’s one thing to be reminded that Apple turned 43 earlier this week. But it’s another when a major anniversary comes around for something which, seemingly, arrived just a couple of months back.

That’s how I feel about the fifth anniversary of ustwo’s Monument Valley. One of the most stunning iOS games yet created, the beautiful puzzle game landed in the App Store this month in 2014. To celebrate its birthday, its creators have given it a neat anniversary update. And thrown in a couple of videos for good measure.

There are hundreds, maybe even thousands, of games available in the App Store. I’ve played tons of them over the years. Some of those games eventually ended up getting deleted, or moved to the last few pages of my games folder, where they remain for long car or plane rides.

However, there are a few games that have remained on my iPhone or iPad’s Home screen for literally years now. Even long after their launch, I still launch these games regularly, play them, and thoroughly enjoy them.

You can usually tell when a game has been well-crafted. A great game will include excellent graphic design, playability, a captivating story and, of course — the soundtrack. A soundtrack can turn a great game into an extraordinary game, captivating the player and immersing them into a world they’ve only dreamt about.

A compelling soundtrack will have amazing melodies, epic chord changes that make you feel something, and sounds that are perfectly tailored to the atmosphere of the game. Below, check out four great iOS games that have amazing soundtracks. I caught up with a few of the soundtrack creators who make these beautiful soundscapes, and their answers to my questions give a ton of insight into how special this music really is.

From a photography app with a difference to a math training app with human curation and a fantastic classic iOS puzzle game going free, we’ve sifted through this week’s most exciting apps to bring you the ones you absolutely need to download now.

Tremendous iOS puzzle game Monument Valley has just gone free on iOS for the first time in its history.

Inspired by the surrealistic designs of M.C. Escher, the title is a triumph of isometric design, in which the player guides a princess through a series of impossible structures in a game that Apple lyrically described as, “akin to a walk through a museum or listening to a music album.”

What do you do as a second act after creating one of the most beautiful iOS games in history? If you’re Ustwo, the devs behind the Cult of Mac favorite Monument Valley, the answer is simple: you redesign the car dashboard.

Yes, you read that correctly.

It might be a long way from the M.C. Escher-inspired iPad puzzle game, but Ustwo has teamed up with the company Car Design Research to create a prototype for a simplified in-car display that shows only the information you need at the time you need it. And, unsurprisingly, it looks spectacular.

One of the biggest reasons why many app developers continue to snub Android is piracy. The platform’s “open” approach, which allows applications to be downloaded from third-party sources and installed manually, makes it incredibly easy for users to circumvent Google Play and obtain paid apps completely free.

Piracy on Android is so rampant right now that just 5 percent of installs of Monument Valley — one of the best mobile games of 2014, which is currently priced at $3.99 in the Play Store — have actually been paid for.

We’ve argued on many occasions before that 2014 was a superlative year for iOS games. But it was also a fantastic twelve months for video games in general, as the last generation’s consoles were pushed to their max, and the PS4 and Xbox 360 hit their stride.

So now that the dust has settled what are our picks for games of the year? Check out our choice of the ten titles you must play after the jump.

Monument Valley is my pick for iOS game of the year; a twisting, gorgeous, MC Escher-style puzzler that’s spellbinding from start to finish. And given that it has received upwards of 1 million downloads, I’m far from alone in thinking that way.

Which is why it’s great to hear that the game is set to receive its first expansion on November 13. Titled “Forgotten Shores,” the expansion will plunge players back into the world of Princess Ida, as she travels through eight entirely new levels, with a slew of fresh puzzles to solve on her journey.
